What is this leak at 40,000 km???

While working on the exhaust I notice a leak at the back, is it serious? my warranty just ended 8 months ago, and he hadn't seen anything on 07/10/2023

Its the differential cover that's sweating. Common issue with these cars and some worse then others. Its a defect in the casting of the cover from BMW. Usually starts in the top left corner.

Solution is to replace the cover with a new updated one.

Thank you for your quick reply. Do you have a part number for the new parts? I can't believe BMW didn't see this during the warranty period.

I'm thinking they couldn't remember and are just BS'ing it to not look bad.
